您需要在超时时取消任务（并中断其线程）。那就是
cancel(true)方法。：
private static final ExecutorService THREAD_POOL = Executors.newCachedThreadPool();private static <T> T timedCall(FutureTask<T> task, long timeout, TimeUnit timeUnit) throws InterruptedException, ExecutionException, TimeoutException { THREAD_POOL.execute(task); return task.get(timeout, timeUnit);}public static void main(String[] args) { try { FutureTask<Integer> task = new FutureTask<Integer>(new Callable<Integer>() { public Integer call() throws Exception { for (int i=0; i < 1000000; i++) { if (Thread.interrupted()) return 1; System.out.println(new java.util.Date()); Thread.sleep(1000); } return 0; } }); int returnCode = timedCall(task, 100, TimeUnit.SECONDS); } catch (Exception e) { e.printStackTrace(); task.cancel(true); } return;}
